Definitions

  • the present invention relates to a container for storing liquid, and more particularly to a container for storing liquid having a function, when an internal liquid remained in the container is discharged, capable of keeping liquid discharging speed approximately constant independently of the amount of the internal liquid and preventing pulsating flow from occurring.
  • a conventional container of this kind for example, there have been a two-mouth container as illustrated in Fig. 22 or a container having an air intake mechanism as illustrated in Fig. 23 (USP 5,340,000).
  • the two-mouth container illustrated in Fig. 22 has such a drawback that both the two mouths have to be opened to make an internal liquid discharge smooth without pulsation when the liquid in the container is discharged.
  • Another drawback is that the two-mouth type container has itself a problem involving rise in production cost because of its shape and a need to provide two caps for each container.
  • the container as illustrated in Fig. 23 has one mouth, but such one-mouth container has a large air-supplying tube which is also used as a handgrip, so that degree of freedom of design is somewhat limited.
  • these conventional containers have common characteristics that air to be supplied into the container is introduced directly into an internal space of the container without passing through the internal liquid.
  • This type of air intake mechanism can realize very smooth discharge of the liquid since there is no resistance caused by the internal liquid when the internal liquid is replaced by air.
  • the discharging speed varies with the height of the surface of the internal liquid. That is, the liquid is discharged at a higher speed at an initial stage of the discharge, when the large amount of the internal liquid is remained in the container. The discharging speed gradually decreases with decrease of the amount of the internal liquid.
  • reference numerals are as follows: 10 is a bottle, 11 is an air channel, 21 is a container mouth portion, 22 is a container body, 23 is a blow-molded portion, 24 is a narrowed portion, 25 is an air port, 31 is discharge port, 35 is liquid, and 40 is air.
  • a container with an air intake mechanism comprising: a blow-molded portion 23, whose opening is larger than that of a container mouth portion 21, is formed by using pressure of a blow molding at a position under the container mouth portion 21; a narrowed portion 24 and a discharge port 31 in the narrowed portion 24 are formed by narrowing down on a container body 22 side portion of the blow-molded portion 23; and an air channel 11 extending from and connecting a side wall of the blow-molded portion 23 positioned over the narrowed portion 24 to an inner upper space of the container body 22; the air channel 11 has such a short length that air 40 supplied through the air channel 11 is released directly in an internal liquid 35 in the container when the internal liquid 35 is discharged.
  • a preferred embodiment of the present invention of the container is characterized in that the narrowed portion 24, the discharge port 31 and an air port 25 are simultaneously formed by narrowing down a side portion of the container body 22 at the blow-molded portion 23.
  • the discharge port 31 has an approximately the same axis along it of the mouth portion 21 and has approximately the same size and shape to the mouth portion 21.
  • Figs. 1A, 1B and 1C three type bottles 10 having different lengths of air channels 11 were prepared for tests.
  • the length of the air channel 11 in Fig. 1A is set at 20 ⁇ 30mm which is the minimum length of necessity for ensuring pulsation-free flow when the internal liquid 35 is discharged; whereas in Fig. 1B, the length of the air channel is about a half of the height of the bottle 10; and in Fig. 1C, the length of the air channel 11 is approximately equal to the height of the bottle 10.
  • Each bottle 10 was nearly fully filled up with liquid 35 and then the bottle 10 was placed upside down shown in Fig. 1A, 1B or 1C to start discharging liquid 35.
  • the surface of liquid 35 was lowering with progress of discharge of the internal liquid 35.
  • Discharging speeds in Fig.1 were measured at each height of the liquid surface indicated by 1 to 6 of measuring points. Discharging speeds were measured in terms of time period during which about 200ml of liquid was discharged from the bottle 10.
  • the test results are shown in the next Table.
  • Each A, B, C in the Table indicates a length of air channel 11 illustrated in Fig. 1A, Fig. 1B and Fig. 1C respectively.
  • the result of the Table is shown in graphs of Fig. 24.
  • the abscissa of the graph indicates Measuring points and the ordinate thereof indicates discharging time by 200 ml.
  • Curve line A is a discharging time used an air channel 11 illustrated in Fig. 1A
  • curve line B is a discharging time used an air channel 11 illustrated in Fig. 1B
  • curve line C is a discharging time used an air channel 11 illustrated in Fig. 1C.
  • the bottle 10 of Fig. 1A of which the length of the air channel 11 is the shortest, the front edge of the air channel is always under the surface of the liquid 35, discharging speed is saved and controlled, showing an approximately constant discharging speed independently of the height of the liquid surface.
  • the liquid 35 was discharged extremely smooth as long as the front edge of the air channel was placed above the liquid surface. Although slight pulsation was observed when the front edge of the air channel was under the surface of the liquid 35, such slight pulsation causes no problem in practical use.
  • Fig. 2A shows a front view
  • Fig. 2B shows a plane view
  • Fig. 2C shows a sectional view taken along a line A-A in Fig. 2A, of a container according to a first embodiment
  • Fig. 3 shows an enlarged sectional view of a mouth portion
  • Fig. 4 is a sectional view taken along a line B-B in Fig. 3
  • Fig. 5 is a sectional view taken along a line C-C in Fig. 3, as well.
  • Fig. 6 is an enlarged sectional view of the mouth portion at a time of discharging an internal liquid 35 according to the first embodiment.
  • a blow-molded portion 23 is formed under a screw portion.
  • Air 40 that is supplied into a container through an air channel 11, is released in the internal liquid 35 remained in the container According to this mechanism, a discharging speed of the liquid can be kept approximately constant independently of the amount of the internal liquid.
  • Fig. 7A shows a front view
  • Fig. 7B shows a plane view
  • Fig. 7C shows a side view of another container according to a second embodiment
  • Fig. 8 is an enlarged sectional view of a mouth portion
  • Fig. 9 is a sectional view taken along a line D-D in Fig. 8
  • Fig. 10 is a sectional view taken along a line E-E in Fig. 8, as well.
  • the blow-molded portion 23 includes the screw portion which is formed by a blow-molding process.
  • the air channel 11 in a rib 26 communicates with both the blow-molded portion 23 and an internal space of a base portion of a handle that is provided at an upper portion of a body 22 of the container.
  • Fig. 11A shows a front view
  • Fig. 11B shows a plane view
  • Fig. 11C shows a side view of still another container according to a third embodiment.
  • the air channel 11 is short in length and compact in size, so that the air channel 11 can be applied not only to a flat square type container but also to a round bilge type container.
  • Fig. 12A shows a front view
  • Fig. 12B shows a plane view
  • Fig. 12C shows a side view of another container according to a fourth embodiment
  • Fig. 13 is an enlarged sectional view of its mouth portion

  • Fig. 15 is a sectional view taken along a line G-G in Fig. 13, and
  • Fig. 16 is a sectional view taken along a line H-H, as well.
  • Fig. 17 is an enlarged sectional view of the mouth portion illustrating a state of discharge, according to the fouth embodiment.
  • an air channel and an air port 25 was formed as an internal space of the blow-molded portion 23.
  • Fig. 18A shows a front view
  • Fig. 18B shows a plane view
  • Fig. 18C shows side view of another container according to a fifth embodiment
  • Fig. 19 is an enlarged sectional view of a mouth portion
  • Fig. 20 is a sectional view taken along a line I-I in Fig. 19
  • Fig. 21 is a sectional view taken along a line J-J in Fig. 19, as well.
  • the air intake mechanism is much more compact in size so that the air intake mechanism can be much easily applied not only to a square type container but also to a round bilge type container.
  • a projection which is peculiar to this type of air intake mechanism, is provided at an inner portion of the mouth, so that it is feared that there may cause a difficulty in inserting a liquid-filling nozzle etc. into the container.
  • the pulsation-free flow when the internal liquid is discharged, can be realized with the one-mouth container. Discharging speed is kept approximately constant independently of the amount of the internal liquid remained in the container, so that there is no need to control the discharging speed by changing the angle of inclination of the container.
  • the air intake mechanism is compact in size, so that the container can be designed more freely.
